SPECIFICATION forming part of Letters Patent No. 610,781, dated September 13, 1898. Application filed December 3l, 1897. Serial No. 665,045. (No model.) Patented in England December 31, 1895, No. 24,976.

To @ZZ whom t may concern,.-

Be it known that I, WILLIAM WHITELEY, a subject of the Queen of Great Britain, residing at Lockwood, Huddersfield, in the county of York, England, have invented certain new and useful Improvements in Machines for Drying Hanks of Yarn, Slivers of Vool, Tops, and other Fibers, (for which I have obtained a patent in Great Britain, No. 24,976,

Vdated December 3l, 1895;) and I do hereby declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to a new form and construction of machine for drying hanks of yarn in a distended state upon rollers or sticks, also for drying sliversof wool, tops, and other ber.

Figure l is a front elevation of my new or improved machine arranged and constructed for drying hanks of yarn. Fig. 2 is a sectional end elevation of same. Fig. 3 is a cross-section through one of the yarn-carriers; Fig. 4, an enlarged view of the feeding end of the machine; and Fig. 5, a sectional plan view of same, taken through line l 2 of Fig. 4.

The machine is inclosed in a wrought-:iron or other chamber 3, and it is provided with steam-pipes 4 for heating the said chamber, 5 being an exhaustfan for drawing air through the chamber. At each side of the machine there are arranged an upper pair of notched stationary bars G and another and lower pair of notched stationary bars 7. These notches receive the ends or axles of rollers, yarn carriers, bars, or Winches 8, around which the hanks 9 are slung, asindicated in Figs. 1 and 2 One end of such rollers or Winches is shown in Fig. 3, and they are divided midway of their length by two disks or plates lO, (sce Fig. 2,) and they are so divided for the purposevof being seized hold of at that particular part by a jaw 11, attached to the upper end of an voscillating lever l2, which jaw, together with the said lever, is capable vof being moved forward toward the feeding end ofthe machine for purposes and in a manner hereinafter more fully described.4 l

Vhen commencing to use the machine, all the notches in the bars 6 and 7 are supplied with rollers or Winches, the jaws ll occupying the position shown in dotted lines, gripping the winch between the disks l0, lodging in the first notch 17. 'Ihe attendant then removes sneck 13 from notch 15, formed in the radial arm 14, after which he pulls the jaws back, as shown in full lines. The dried hanks lare now removed and the wet hanks are slung lon to each end of the winch, when the operative pushes the said jaw forward, as indicated in dotted lines, so that the sneck enters the notch 15, the pin 1G acting as a stop-piece to prevent the jaws moving too far. When the said jaws have been moved forward, the outer ends or axles of the winch drop into the first notch 17 of the lower notched bar 7, and simultaneously with this movement the lever l2, which is fast upon shaft 1S, causes the said shaft to rock, in doing which the short lever 19 is brought down, pulling the rod 2O downward and operating the bell-crank lever 2l, making the horizontal rod 22 to move for ward endwise, whereby the strap-fork 23, attached thereto, slides the driving-strap from the loose pulley 24 to the fast pulley 25. Consequently the machine is set in motion selfactingly every time a fresh roller is put into the machine. When the machine has been thus set in motion, the spur-wheel 26 is made to rotate from pinion 27, which pinion receives its motion from the bevel-gearing 28 and horizontal shaft 29 and spur-wheels 30, driven from the main shaft 3l. When the spur-wheel 26 revolves, the Yconnecting-rod 32, attached thereto, causes the pinion 33 to revolve and to roll in the teeth of the stationary rack 34 g but the other rack 35 is free to slide up and down in the slide 36, and this is eifected through the medium of the connecting-rod 32 and pinion 33. Soon after the rack 35 commences to descend the cam 37 at the back of the wheel 26 operates the vertical rod 38, connected by studs to the slide 36. This cam 37 and rod 38 are employed for the pur-- crum 39, causing the lower end of the slide IOC) to come inward and the upper end to go outward, so as to permit the hooked lug 40 to get below and underneath each end of a winch 8 when lodging in notch 17 of the lower notched bar 7, and when this is effected-4l. e., when the lug 40 on rack 35 has got hold of a Winchthe toothed wheel 26 will have arrived at such a position in its rotation that the connectingrod 32 begins to ascend, taking the sliding rack 35, together with the winch charged with wet hanks, upward until the lug 40 gets above the first notch 41 in the top notched bar 6. When this has been accomplished, the cam 37 causes the lower end of the slide 36 to go outwardly and the upper end ofthe said slide to be moved inwardly, so as to drop the ends of the Winch in the first notch 41 of the top notched bar 6. After this operation has taken place, which is performed with one revolution of the Wheel 26, a finger 42 is caused to rotate upon the shaft 43, driven by chain 44 from the chain-wheel 45 on the shaft 46. The said finger 42 lifts the forward end 47 of the strap-fork rod 22 from off the holdin g-pin 48, whereupon a spiral spring 49 (shown in Fig. 5) draws the strap-fork from the fast to the loose pulley and stops the machine self-actingly. While these various motions just described are being performed, a second pair of top and bottom horizontal notched bars 50 and 5l have been transferring (if the machine was full) the whole series of Winches, together with their hanks, from one notch to another notch in the stationary bars 6 and 7, and this is effected in the following manner: Horizontal shafts 52 and 53,driven by bevel-wheels 54 from the bottom shaft 29, are employed,

and on these shafts 52 and 53 are bevel-wheels` 55 and 5 6, driving other bevel-wheels 57 and 58, carrying eccentrics 59 and short lever 60, the opposite end of which short lever is connected to the movable notched bars 50 and 51 by stud ct, which notched bars are lifted upward by the levers 60, the notches in said bars seizing hold of the axles of the Winches and carrying them half a revolution and dropping the axles of the said Winches into the next succeeding notches, this being done for the purpose of causing the Winches andhanks to be traversed or handed forward through the machine, this operation taking place simultaneously with both the top and bottom series. At the completion of each revolution of Wheel 26 and when the machine has been stopped the endmost notch 41 in the top notched bar 6 will be empty, as the winch of wet hanks which has just been lifted from the bottom notched bar 7 will have been transferred into the second notch in the top bar. The notch 17 Will at this time contain a Winch of dried hanks which have just been transferred by the lifting-bar 51, the jaw 11 having hold of the said Winch. The workman then withdraws the jaws 11, as indicated in full line in Fig. 4, when he will strip the dried hanks, replacing them with Wet hanks, and afterward he Will put the said winch back again into notch 17. This operation restarts the machine, causing the rack 35 to descend, as already explained, to take hold of the newly-charged winch to lift it up to notch 41,

when the machine will again be stopped selfactingly. This stopping and restarting of the machine goes on so long as the machine is at Work.

The modus operand/i is as follows: lf the machine has been at work, all the Winches are charged with hanks, the jaws 11 having hold of the winch in the notch 17 The workman then withdraws the jaws, together with a winch charged with dried hanks, which are stripped and wet ones substituted. The workman then transfers the newly-charged winch into the first notch 17 of the bottom bar. The rack 35 then comes down,placin g the lug40 underneath the ends of the Winch; but to permit this to be done the slide 36 oscillates on its fulcrum for the hook to get past the Winch, when by the continued rotary motion of the machine the lug 40 lifts up the hank to the first notch 41 in the top bar 6. Meanwhile the slide 36 moves, as explained, to permit this to be done, and simultaneously with that movement the notched bars 50 and 51 are transferring the whole series of Winches in both top and bottom sets of bars from one notch to another in the direction of the arrows. The machine then stops self-actingly, as described, when the operation of removing dried hanks and placing Wet ones in the first notch is again performed. When the hank-carrying rollers have been transferred from notch to notch bythe lifting notched bars 50 and 51, the end hank-roller A, with hanks, are transferred from the endmost notch B in the top range to the endmost notch C in the lower range, the operation being performed in the same manner as the feeding end of machine, excepting that in this case instead of the hanks being raised they are lowered. The tappet 37, Wheel 26, and connecting-rod 32 correspond to those already described at the feeding end of the machine.

It will be understood from the above description that the rollers and hanks are de'- livered out of the machine at the bottom row at the same point at which they enter, and the hanks never leave the machine except to be stripped, which is easily done, as the rollers are free at each end, While wet hanks can also be easily substituted.

The whole of the machine or apparatus is inclosed in suitable metal sides and frame- Work, and hot air is given off by pipes 4, such hot air being made to circulate by the use of fan 5. It will be obvious that instead of the hanks being transferred from one notch to another by the notched bars 50 and 51 the latter may be dispensed with and endless chain employed instead.

Although I have shown and described the machine as being applicable for drying hanks of yarn, slivers, tops, and other fibers may be effectually dried in the same machine.,
